600 m2 Q water 200 l/s Q air 90 l/s Data acquisition systems Tools storage

The hydraulic engineering laboratory, located in the building 4J in the UPV, has an indoor area of 600 m2 where a tools' storage, a teaching area, an area with several experimental channels to develop test campaings reagarding research projects, and a third area with physical models mainly dedicated to urban hydraulics can be found.

Teaching area

The teaching area in the laboratory is dedicated to the realisation of practical lectures corresponding to different degrees at the UPV. Currently, the laboratory takes in practical lectures from the following degrees:

• Civil Engineering Degree
• Technical Civil Engineering Degree
• Civil engineering Masters Degree
• Hydraulic Engineering and Environment Masters Degree

The modules corresponding to this degrees, which are related to the activity in the laboratory are, mainly Hydraulics and Hydrology, River Engineering, Hydraulic Constructions, Dams and River hydraulics and River restoration. The laboratory has capacity for 25 students.


Research area

Inside the laboratory there are channels to perform the experimental tests corresponding to different research projects. Among them, the following can be highlighted:

• A main channel with variable slope, which runs longitudinally through the laboratory, from the inlet tank in the indoor area. The channel is 20 m long with rectangular section of 0.80 m wide and 0.50 m high. The feeding system of the channel has a pumping capacity of 70 l/s and is equiped with gate-spillway downstream to stablish different boundary conditions. The channel presents a blade system in the entrance so that it can be operated with variable flow rate.

• An experimental channel for multiphase flows, with a pumping capacity of 140 l/s for water, and 90 l/s for air. The feeding and the mixture water-air is done under pressure. At the entrance of the channel, there is a transition between pressure and free surface flow. The channel is 10 m long, with rectangular section of 0.30 m wide and 1 m high. It is equiped with limnimeters, Doppler velocimeters, pressure sensors, a fiber optic sensor and equipement to apply digital image processing (with edge detection methods).

• A sedimentological channel for the tridimensional study of ersoion and sedimentation processes in riverbeds. With a working area of 4 m long y 0.60 m wide, and a pumping capacity of 4 l/s. It is equiped with digital limnimeters, instrument holder and rails throughout the channel borders. Terrestrial photogrammetry techniques can be also applied based on images taken with digital reflex cameras in order to restore the tested scour pits.

• An experimental channel for multiphase flows, with a pumping capacity of 3 l/s, 3 m long y 10 cm wide with rectangular section. There is a compressor in order to supply with different air flow rates. It is equiped with a flow separator upstream so that an appropiate transition from pressure to free surface flow can be guaranteed.

• A sedimentological channel of 2.5 m long y 6.4 cm wide, with a pumping capacity of 1 l/s, for the simulation of scouring processes in structures placed in riverbeds.

The channels are equiped with pressure sensors, fiber optic, Doppler velocimeters, analogue and digital limnimeters and cameras.


Physical models area

In the indoor area of the laboratory there is a space available for reduced physical models, such as those corresponding to structures in the field of urban hydraulics. These models are connected to the pumping equipement in the indoor area, and the return is connected to the laboratory's underground water storage, forming a closed hydraulic circuit. Currently the reduced physical model at scale 1/20 of part of the Valencian South Sewer Pipe is operational.


In the indoor area of the laboratory there is also the tools storage, where machines and tools needed for the construction and operation of the elements that form the reduced models can be foundd. Moreover, in the first stage there is the researchers and the technicians offices. Apart from the corresponding IT and specific software software equipement to develop the numerical simulations, the offices have the necessary space and facilities to be used as a meeting room.



1000 m2 Q water 200 l/s Data acquisition system

The outdoor area of the laboratory has a surface of approximately 1000 m2, it is connected to a pumping equipement with capacity of 200 l/s and it has a channel network in order to return the pumped flow rate to the underground water storage, so that each model works with a closed hydraulic circuit. In this area the largest models can be found, corresponding to dams and channelizations.

Dams and channelizations physical models

Currently, the following models can be found in the outdoor area of the laboratory:

• Channelization of the Mandor's ravine (Valencia)
• End of the Aren?s reservoir(Castell?n)
• Terrateig's dam in river Vernissa (Valencia)
• Oliva's dam sobre in la Gallinera's ravine (Valencia)

The characteristics of each of them, as well as the previous models created in the laboratory, can be seen in the section Projects.
